Verdict

The SMEG ST4523IN is a 45 cm slimline, fully-integrated built-in dishwasher from the Universale collection featuring a 10 place-setting capacity, an Inverter motor, and a stainless steel inner tank. It operates with 8 wash programs (including Eco, Express, and Intensive cycles) at a relatively quiet noise level of 46 dB, utilizing 9.9 liters of water and 0.75 kWh of energy per eco cycle. Its primary pros include a discreet design with Flexifit sliding hinges, an automatic Dry Assist door opening system for natural condensation drying, an Aquatest turbidity sensor, and a floor-projected ActiveLight end-of-cycle indicator. On the downside, it carries a modest Class E energy efficiency rating and features a lengthy 4:00-hour eco program duration.
